The Deep X-ray Radio Blazar Survey (DXRBS). II. New Identifications
H. Landt, P. Padovani, E. Perlman +3
We have searched the archived, pointed ROSAT Position Sensitive Proportional Counter data for blazars by correlating the WGACAT X-ray database with several publicly available radio…
Surveys and the Blazar Parameter Space
E. S. Perlman, P. Padovani, H. Landt +5
The rareness of blazars, combined with the previous history of relatively shallow, single-band surveys, has dramatically colored our perception of these objects. Despite a quarter-…
The Optical-Near-IR Spectrum of the M87 Jet From HST Observations
Eric S. Perlman, John Biretta, William Sparks +2
We present 1998 HST observations of M87 which yield the first single-epoch optical and radio-optical spectral index images of the jet at resolution. We find $<α_{ro} > \ap…
The X-ray evolution of clusters of galaxies to z=0.9
L. R. Jones, H. Ebeling, C. Scharf +6
The evolution of the X-ray luminosity function of clusters of galaxies has been measured to z=0.9 using over 150 X-ray selected clusters discovered in the WARPS survey. We find no…
Astronomical Constraints on the Cosmic Evolution of the Fine Structure Constant and Possible Quantum Dimensions
C. L. Carilli, K. M. Menten, J. T. Stocke +6
We present measurements of absorption by the 21cm hyperfine transition of neutral hydrogen toward radio sources at substantial look-back times. These data are used in combination w…
The Properties of the X-Ray-Selected EMSS Sample of BL Lac Objects
T. A. Rector, J. T. Stocke, E. S. Perlman +2
We present updated and complete radio, optical and X-ray data for BL Lacs in the Einstein Medium Sensitivity Survey (EMSS). The complete "M91" sample first presented in Morris et a…
